This invention ieiarastmhoerscrubbm g 5 devices and the ohj''ctot't'the invention is to provide a device of this character mounted .upon a wheeled truck, and whichis adapted to be operated as the truck is propelled.

Another object of the invention is to provide a device of this character which is simpie-in construction, comparatively cheap to manufacture and which will erform the functions for which it is inten ed with accuracy and eflici'ency.

With the hove and-other objects in view which will appear as the description progresses the invention resides in the novel In the accompanying drawing, Figure 1 is a side elevation of the devlce constructed in accordance with the present invention. Fig.

ing broken away and shown in section, and in dotted lines to more clearly illustrate the sectional view of one of the scrubbing Referring to the drawings the numerall designates the truck of the device.- This truck 1-.is provided with forward wheels 2 and rear wheels 3. The axles of these wheels are provided with suitable upstanding members 4 and 5 whereu on the body 5 of the truck is supported. '(Jonnecting'. the axles of the wheels .is a substantially "V- forward axle of the device. This forward axle is also provided with a handle 8 whereby thedevice is operated in'a manner here- By'reference to Fig. 2 of the drawingi will be noted that the rear axle, designated by the numeral 9 is provided with oppo; sltely disposed ofisets 10 which are adapted nected to collars 12 provided upon the proiecting stems 13 of the scrubbingbrushes' 14. lflhe stems 13 of these brushes learehollow and are each provided with a threadedaperituf wan-awaitsis possesses nirmea e'lein'entilt. nae-h of the stains 13" are connected througntlie medium 01' tlfi isinemher-1'5 with a'tuoe idem these tunes has its 'upperportioniprovidecl with a suitable T 1 7 'whetebyitne-members are connected'w'itn a delivery pipe 1a supported upon the rear ort on oit'h-e hod-y fi of the track.' This eiiverypip'e' iBha's tool of its ends closed and is mounted in suitable'hr'ackets"1'9 arranged adjacent the sides of the body 5. By reference to Fig. 2 it will be noted that the tube members 16. extend downwardly through longitudinal slots pro .vided by the body 5 of the device. The delivery pipe 18 is centrally provided/with a suitable T connection 21 and thisT is adapted forengagement with a valve pipe 22, which communicates with a water receptacle 23. i a

The bottom ortion of the stem 13 is enlarged as clear y shown in the figures of the drawing and the base of this portion is provided with a plurality of openings 24.

From the above noted that as the 'wheels of the device are rotated the brushes 14 through the medium of the ofiset portions 10 of the rear shank 9 and the links 11 will be oscillated in op posits directions and it is to he understood that water contained within the receptacle 23 is fed through the ipes 22 and 18 to the tube 16 connected wit the stern 13 01- the brush 14. It will be further noted that the amount of water or sapon aceous flui clfed to the brushes may be readily regulated escription, it will hethrough the medium of the valve connected 7 with the pipe 22.

' In order to prevent the brushes from splashing the water I have rovided the rear of the body swith a hinge apron 25, This apron 25 is adapted to be retainedina substantially vertical position through the me dium of a hook 26 engagin an eye 27 provided upon, the sides of; the ody 5.

Having thus fully described the invention what is-claimed as no; is: 1'. In a device at the purpose set forth, awheeled truck having front and rear axles, the rear axle being provided with o positely disposed offsets, brush members connected with the truck, and links connecting the brush members withthe ofi'sets' of the axle.

2. In a device for the purpose intended,"

mgedly a wheeled truck having frontand rear axles,

end Wheels therefor,

the rear axle being provided with oppositely disposed ofisets, a tank u on the truck, sup ports hingeclly connecte with the truck, a, brush carried by each supoort, a hollow connection between the brus es and the tank, and links connecting the brush members with the offsets of the rear axle.

3. A truck having front and rear axles the rear axle being pro vided with oppositely arranged ofisets, a. water receptacle upon the truck, a pair of brush sup ortxs hingedly connected with the truck, eac comprising hollow and acljustable tubes, a brush carried b Y each support, means for conducting fluid irom the receptacle to the hollow supports and links pivotell connected with the 0 "sets of the rear ax e, adapted to impart oscillatory motion to said brushes.

purpose set forth, at M the rear axle being provided. with oppositely disposed oflfsets, e

water rece tecle upon the truck, telescoping tube Inem ers hingedly cormected with the truck, a valved communication between the tank and the tube members, brushes ro' vided with perforated heeds eonnecte to and in direct communication with the interior of the tube members, and links pivotally connected with the tube members and with the offsets of the rear axle.
